Semiconductor = e Ny LH2110/LH2210/LH2310 z= gS Dual Voltage Followers £ iS o General Description Features S ‘The LH2110 series of dual voltage followers are two LM110 Low input current 17A type followers in a single hermetic package. Featuring all ™ High input resistance 10109 the same performance characteristics of the single, these im High slew rate 30V/ps duals oner in addition closer thermal wacko, lower weight @ Wide bandwidth 20 MHz reduced insertion cost and smaller size than two sing] Wi i +5V to +18V For additional information, see the LM110 data sheet and Output shart reat oot ° National's Linear Applications Handbook. Pre The LH2110 is specified for operation over the —55°C to +125°C military temperature range. The LH2210 is speci- fied for operation over the —25°C to +85°C temperature range. The LH2310 is specified for operation over the 0°C to +70°C temperature range.

For operating devices in the flat package at elevated temperatures, the derating is based on @ thermal resistance of 185°C/W when mounted on @ '/~inch-thick epoxy glass board with 0.03-inch-wide, 2-ounce copper conductors. The thermal resistance of the dual-in-line package Is 100°C/W, junction to ambient. : ‘Note 2: For supply voltages less than + 15V, the absokite maximum input voltage Is equal to the supply voltage. : Note 3: Continuous short circuit is allowed for case temperatures to 125°C and ambient temperatures to 70°C . It is necessary to insert a resistor greater than 2 k2 : in series with the input when the amplifier is driven from low impedance sources to prevent damage when the output is shorted. Note 4: These specifications apply for +5V < Vg < +18V and —55°C < T, < 125°C, unless otherwise specified. With the LM210, however, all temperature ‘specifications are limited to — 26°C < Ta < 85°C, and for the LH2310, all temperature specifications are limited to °C < Ta < 70°C. Note 5: Increased output swing under load can be obtained by connecting an external resistor between the booster and V— terminals. 4-20
